	revised 2005 Nov 04 by Laurence: allow hyphens before @ symbol; rename 'verifyEmail' to 'validateEmail'

	RegExp is a Javascript1.2 feature; tested successfully in WinIE 5.0+, MacIE 5.1, Safari 1.0, WinNN 4.7, WinNN 6.2, WinMoz 1.7
	The pattern matches: 
	- at least one word character ( a-zA-Z0-9_ )
	- followed by any number more including periods and hyphens
	- then a single @
	- then at least one alphanumeric character plus any number more including hyphens and periods
	- plus an ending of an alphanumeric char, a single period, and at least 2 more letters. 
	There can be nothing before or after the pattern; all whitespace, punctuation, etc. not explicitly allowed is forbidden.
